    • A mobile wireless communications device may include a housing and a multi-frequency band antenna carried within the housing. The multi-frequency band antenna may include a main loop conductor having a gap therein defining first and second ends of the main loop conductor, a first branch conductor having a first end connected adjacent the first end of the main loop conductor and having a second end defining a first feed point, and a second branch conductor having a first end connected adjacent the second end of the main loop conductor and a second end defining a second feed point. A third branch conductor has a first portion within the main loop conductor, and a second portion connected to the second feed point. A tuning branch conductor may have a first end connected to the main loop conductor between the respective first ends of the first and second branches.
    • 移动无线通信设备可以包括在壳体内承载的壳体和多频带天线。 多频带天线可以包括主环导体,其中具有限定主环导体的第一和第二端的间隙,第一分支导体,其第一端连接在主环导体的第一端附近,并且具有第二端 限定第一馈电点,以及第二分支导体,其具有连接在主环路导体的第二端附近的第一端和限定第二馈电点的第二端。 第三分支导体具有在主回路导体内的第一部分,以及连接到第二馈电点的第二部分。 调谐分支导体可以具有连接到第一和第二分支的相应的第一端之间的主环路导体的第一端。
